In the initial state, the C-shaped plug plates are all located at the lower part of the inner frame; when the operator inserts the shelf into the corresponding C-shaped plug plate, the tooth groove is meshed with the corresponding driving gear, and the driving gear is driven to rotate forward, thereby driving the corresponding shelf to rise, and vice versa, when the operator pulls the shelf from the inside and outside of the C-shaped plug plate, the driving gear rotates in the opposite direction, thereby driving the corresponding shelf to descend, so that when the shelf is at the lower part of the inner frame, it is convenient for the operator to store and retrieve medicines on the shelf, and the operation is convenient.

[0008] Preferably, the driving gear includes a gear body and a bearing seat, the gear body part passes through the corresponding avoidance hole and then meshes with the tooth groove, a rotating shaft is provided in the center of the gear body, one end of the rotating shaft is fixedly connected to the gear body and is located in the inner frame, the gear body is rotatably connected to the bearing seat through the rotating shaft, the bearing seat is slidably connected to the corresponding side wall of the inner frame up and down, the C-shaped plug plate is supported on the corresponding bearing seat, rectangular grooves are provided on the left and right sides outside the inner frame, the other end of the rotating shaft passes through the bearing seat and is located in the corresponding rectangular groove and is provided with a winding area, a pull rope is provided in the rectangular groove, the pull rope is parallel to the height direction of the inner frame, one end of the pull rope is detachably and fixedly connected to the top of the rectangular groove, and the other end of the pull rope is wound and connected in the winding area. When the operator inserts the shelf into the corresponding C-shaped plug plate, the tooth groove meshes with the corresponding gear body, and the gear body drives the rotating shaft to rotate synchronously in the positive direction. Under the action of the pull rope, the bearing seat and the gear body rise along the side wall of the inner frame. Since the C-shaped plug plate is supported on the corresponding bearing seat, the corresponding shelf is driven to rise at the same time as the bearing seat rises; conversely, when the operator pulls the shelf from the inside and outside of the C-shaped plug plate, the gear body drives the rotating shaft to rotate synchronously in the opposite direction, thereby driving the corresponding shelf to descend under the action of the pull rope, so that when the shelf is at the lower part of the inner frame, it is convenient for the operator to store and retrieve medicines on the shelf, and the operation is convenient.

[0009] Preferably, the other end of the pull rope is wound around the winding area from the rear side of the low temperature box to the front side of the low temperature box for one circle and then detachably fixedly connected to the bottom end of the rectangular groove.

[0011] Preferably, the winding area is provided with conical wheel one and conical wheel two, the conical wheel is set on the corresponding rotating shaft and fixedly connected to the rotating shaft, the conical wheel two is provided with an external threaded column, one end of the external threaded column is fixedly connected to the center of the conical wheel two, the other end of the external threaded column is located in the inner frame and is sleeved with a nut, the external threaded column successively penetrates the center of the corresponding rotating shaft and the center of the corresponding gear body and is threadedly connected to the nut, the conical wheel two is elastically connected to the conical wheel one, the conical wheel one and the conical wheel two are symmetrically distributed on the left and right to jointly form an annular groove with a V-shaped cross-section, and the pull rope is wound in the annular groove. Since an annular groove with a V-shaped cross section is formed between the conical wheel one and the conical wheel two, the operator changes the distance between the conical wheel one and the conical wheel two by adjusting the nut to adjust the inner diameter of the pull rope wound in the annular groove. The larger the inner diameter, the greater the stroke of the shelf rising or falling, and the smaller the inner diameter, the smaller the stroke of the shelf rising or falling, thereby achieving the effect of regulating the spatial position between adjacent shelves, which is convenient for improving space utilization; the conical wheel two and the conical wheel one can be elastically connected by setting elastic parts such as springs, so that the operator can change the distance between the conical wheel one and the conical wheel two by adjusting the nut.

The larger the inner diameter, the greater the stroke of the shelf 4 rising or falling, and the smaller the inner diameter, the smaller the stroke of the shelf 4 rising or falling, thereby achieving the effect of regulating the spatial position between adjacent shelves 4, which is convenient for improving space utilization; the conical wheel 2 16 and the conical wheel 1 15 can be elastically connected by setting elastic parts such as springs, so that the operator can change the distance between the conical wheel 15 and the conical wheel 2 16 by adjusting the nut 18.

[0036] In the fifth embodiment, the width of the shelf 4 is smaller than the length of the C-shaped plug plate 23. This is conducive to further improving the amplitude of the rise or fall of the shelf 4. The number of shelves 4 can be any number of pieces, and the shelf 4 at the bottom of the inner frame 3 can be fixed by bolts without frequent adjustment after adjusting the position by sliding.
